摘要 |
The present invention provides a method for storing holographic data comprising providing an optically transparent substrate comprising a photochemically active dye and a photo-acid generator; irradiating the optically transparent substrate with a holographic Interference pattern, wherein the pattern has a first wavelength and an intensity both sufficient to convert, within a volume element of the substrate, at least some of the photochemically active dye into a photo-product, producing within the irradiated volume element concentration variations of the photo-product corresponding to the holographic interference pattern, thereby producing a first optically readable datum corresponding to the volume element; and irradiating the optically transparent substrate at a second wavelength and intensity sufficient to activate the photo-acid generator to stabilize the optically readable datum. |
